Scope
This criterion is applicable to the evaluation and testing of products that use charcoal containing filler fiber textiles for warmth retention as a major feature, including various bedding products such as quilts, pillows and quilted bedspreads as well as various clothing products such as quilted jackets and quilted pants.
Note: The applicant must also provide a non charcoal containing filler fiber as the control specimen. The grade, composition and structure of the control specimen must be the same as those of the test specimen.
Terminology:
“Charcoal containing filler fiber textiles for warmth retention” refer to the products that claim warmth retaining effects through the incorporation of charcoal containing synthetic fibers as fillers, including various bedding products such as quilts, pillows and quilted bedspreads as well as various clothing products such as quilted jackets and quilted pants.
Performance specification
Qualified products under this criterion are classified into two types:

|
Qualitative Analysis of Charcoal Content
|
Treat the fiber specimen based on CNS 2339 L3050 (Method of Test for Mixing Ration of Fibers Mixtures). Dissolve the synthetic components of the fiber. Collect the insoluble objects and observe them via SEM-EDX or micro-Raman spectroscopy; we shall be able to find the element carbon.

|
Far Infrared Features
|
Far Infrared Spectral Emissivity
|
The stable average emissivity of light waves with the wavelength of 2~ 22Mm is not less than 0.80 as measured by Far Infrared spectrophotometer.
|
|
Temperature Increasing Feature
|
Difference in temperature between the test specimen and the control specimen is not less than 2 degrees Celsius.
